Abstract
Purpose The purposes of this study were to investigate whether the use of immune checkpoint inhibitors (ICIs) in advanced non-small-cell lung cancer (NSCLC) would increase the possibility of archiving complete response (CR) and assess the surrogate end points for overall survival (OS). Methods We calculated the incidence and relative risk (RR) of CR events in patients assigned to ICIs compared to that in controls. Simple linear regression models were fitted for median OS and each surrogate (median progression-free survival [PFS], CRs, and objective response rate [ORR]). Results A total of 4,803 NSCLC patients from nine randomized controlled trials (RCTs) were included for analysis. The incidence of CR in NSCLC patients treated with ICIs was 1.5% (95% CI: 0.8–3.0) compared to 0.7% (95% CI: 0.4–1.2) in chemotherapy (CT) groups. The use of ICIs in advanced NSCLC significantly improved the possibility of archiving CR (RR 2.89, 95% CI: 1.44–5.81, P=0.003) compared to CT. Subgroup analysis according to ICIs showed that the use of atezolizumab (RR 3.26, P=0.01) and nivolumab (RR 4.83, P=0.042) in advanced NSCLC significantly improved the CR rate in comparison with CT alone, but not pembrolizumab and ipilimumab. We also found that the use of ICIs as first-line (RR 2.39, 95% CI: 1.08–5.3, P=0.032) or second-line (RR 4.99, 95% CI: 1.10–22.66, P=0.038) therapy significantly increased the change in obtaining a CR. In addition, correlation analysis indicates that PFS was strongly correlated with OS in NSCLC patients who received ICIs (r=0.89 for PFS, P=0.017). No marked correlation was found between OS and CR (r=0.19, P=0.75) and OS and ORR (r=0.52, P=0.28). Conclusion The CR is a rate event in advanced NSCLC, but the use of ICIs significantly increases the possibility of archiving CR in comparison with CT. PFS is significantly correlated with OS and could be used as a surrogate end point, but not for CRs and ORRs.

Abstract
Lung carcinoma is the leading cause of cancer mortality for both genders in the United States and throughout the world. Many of these tumors are being diagnosed with minimally invasive means resulting in small samples. There is a need to extract an increasing amount of therapeutic and prognostic information from progressively smaller samples. Collaboration among clinicians and pathologists is needed to produce a comprehensive final diagnosis in patients with lung cancer. This collaboration facilitates triage of small samples for ancillary studies including molecular testing. What follows represents a review of the current required testing for lung cancer specimens, an example of an algorithm currently employed at the Cleveland Clinic so that all required tests can be performed even on the smallest of specimens and suggestions on how pathologists may approach this new era of "doing more with less".

Abstract
INTRODUCTION Non-Small Cell Lung Cancer (NSCLC) is commonly diagnosed in patients who have survived a prior malignancy. However, it is currently unclear whether NSCLC patient survival is impacted by the potential for previously-treated malignancies to recur. Understanding the impact of a prior cancer history on NSCLC survival could not only enhance decision making but could affect eligibility for NSCLC studies. METHODS The National Cancer Database (NCDB) was queried for NSCLC patients (stage I-IV) diagnosed between 2004-2014. Kaplan-Meier survival curves and multivariable Cox proportional hazards regression models were estimated to analyze overall survival across a variety of treatment approaches and stages in the presence and absence of a prior cancer history. RESULTS A total of 821,323 patients with a newly diagnosed NSCLC were identified including 179,512 (21.9%) with a prior history of cancer. The unadjusted 5-year overall survival of patients with a prior cancer history (9.8%) was slightly better to those without a cancer history (9.5%, 95% CI 11.76-11.84, P < 0.0001). However, adjusted analyses revealed the impact of prior cancer history was extremely heterogenous across stage and treatment approach. Ultimately, 51.4% of patients fell into a subgroup in which prior cancer history appeared to compromise survival, 16.3% in which the difference was not significant, and 32.3% in which prior cancer was associated with increased survival. Patients with earlier-staged tumors were the most negatively NSCLC impacted by prior cancer history. CONCLUSIONS The association between prior cancer history and survival of newly diagnosed NSCLC patients is highly variable and to some degree reflects a patient's potential for cure.

Abstract
Lung cancer is one of the most common types of cancer with one of the highest incidence and mortality rates. Gefitinib is widely used for the treatment of non-small cell lung cancer (NSCLC). However, issues regarding drug resistance, toxicity and limited applicability have been associated with gefitinib. The aim of the present study was to investigate whether ginsenoside Rg3 enhances the anticancer activity of gefitinib in NSCLC cells. MTT assay demonstrated that ginsenoside Rg3 increased the cytotoxic effect of gefitinib in NSCLC cell lines in a dose- and time-dependent manner. In addition, flow cytometric analysis revealed that the combined treatment with gefitinib and ginsenoside Rg3 significantly increased apoptosis in NSCLC cell lines. Transwell migration assays demonstrated that the combined treatment with gefitinib and ginsenoside Rg3 significantly decreased NSCLC cell migration compared with gefitinib or ginsenoside Rg3 treatment alone. Furthermore, western blot analysis revealed that in NSCLC cell lines, the combined treatment with gefitinib and ginsenoside Rg3 increased protein expression levels of pro-apoptotic proteins Bax and cleaved-caspase-3, whilst the expression level of anti-apoptotic protein Bcl-2 decreased. In addition, western blot analysis revealed that, in NSCLC cell lines, the combined treatment with gefitinib and ginsenoside Rg3 decreased the protein expression levels of pro-migration factors SNAIL and SLUG, whilst the expression level of anti-migration protein E-cadherin increased. In conclusion, ginsenoside Rg3 may be able to enhance the anticancer activity of gefitinib, making NSCLC cells more sensitive to gefitinib.

Abstract
OBJECTIVE The purpose of this study is to directly compare the capability of gadolinium-based blood volume (BV) mapping from MRI (BV-MRI) with ultrashort TE (UTE) with that of CT and perfusion SPECT in predicting the postoperative lung function of patients with non-small cell lung cancer (NSCLC). SUBJECTS AND METHODS Unenhanced and contrast-enhanced MRI with UTE, thin-section CT, and perfusion SPECT examinations and measurements of the percentage of forced expiratory volume in 1 second (FEV1) before and after lung resection were performed for 29 patients with NSCLC (16 men [mean age, 66 years] and 13 women [mean age, 66 years]). BV-MRI with UTE was generated as a percentage of the signal change between unenhanced and contrast-enhanced MRI. The postoperative percentage of FEV1 was predicted from perfusion fractions derived from BV-MRI with UTE and from SPECT. Quantitatively and qualitatively predicted postoperative percentages of FEV1 from CT were calculated from the functional lung volumes and the number of segments. Each predicted postoperative percentage of FEV1 was then correlated with the actual postoperative percentage of FEV1, and the limits of agreement for each actual and predicted postoperative percentage of FEV1 were evaluated by Bland-Altman analysis. RESULTS Correlations between actual and predicted postoperative percentages of FEV1 for all methods were strong and significant (0.88 ≤ r ≤ 0.95). The limits of agreement (mean ± 1.96 × SD) for BV-MRI with UTE (4.2% ± 6.5%) and quantitatively assessed CT (4.1% ± 6.5%) were smaller than those for qualitatively assessed CT (4.2% ± 9.8%) and perfusion SPECT (5.7% ± 8.7%). CONCLUSION BV-MRI with UTE has the potential to predict the postoperative lung function of patients with NSCLC more accurately than qualitatively assessed CT and SPECT, and it can be considered to be at least as useful as quantitatively assessed CT.

Abstract
Purpose We performed a systematic review and meta-analysis to investigate the efficacy of third-line treatment for advanced non-small-cell lung cancer (NSCLC). Materials and Methods Relevant trials were identified by searching electronic databases and conference meetings. Prospective randomized controlled trials (RCTs) assessing third-line therapy in advanced NSCLC patients were included. Outcomes of interest included overall survival (OS) and progression-free survival (PFS). Results A total of 1,985 advanced NSCLC patients received third-line treatment from 11 RCTs were included for analysis. The use of single targeted agent as third-line therapy for advanced NSCLC did not significantly improved PFS (HR 0.75, 95% CI: 0.28–2.04, p = 0.58) and OS (HR 1.01, 95% CI: 0.86–1.17, p = 0.95) when compared to docetaxel alone. In addition, erlotinib-based doublet combination therapy did not significantly improved PFS (HR 0.94, 95% CI: 0.78–1.13, p = 0.49) and OS (HR 1.08, 95% CI: 0.78–1.51, p = 0.65) in comparison with erlotinib alone. Conclusions The findings of this study show that the efficacy of single novel targeted agent is comparable to that of docetaxel alone in terms of PFS and OS for heavily pretreated NSCLC patients. In addition, no survival benefits are obtained from erlotinib-based doublet therapy, thus single agent erlotinib could be recommended as third-line treatment for unselected advanced NSCLC patients.

Abstract
Resistance to epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs), such as erlotinib and gefitinib, is a major clinical problem in the treatment of patients with non-small cell lung cancer (NSCLC). YM155 is a survivin small molecule inhibitor and has been demonstrated to induce cancer cell apoptosis and autophagy. EGFR-TKIs have been known to induce cancer cell autophagy. In this study, we showed that YM155 markedly enhanced the sensitivity of erlotinib to EGFR-TKI resistant NSCLC cell lines H1650 (EGFR exon 19 deletion and PTEN loss) and A549 (EGFR wild type and KRAS mutation) through inducing autophagy-dependent apoptosis and autophagic cell death. The effects of YM155 combined with erlotinib on apoptosis and autophagy inductions were more obvious than those of YM155 in combination with survivin knockdown by siRNA transfection, suggesting that YM155 induced autophagy and apoptosis in the NSCLC cells partially depend on survivin downregulation. Meanwhile, we found that the AKT/mTOR pathway is involved in modulation of survivin downregulation and autophagy induction caused by YM155. In addition, YM155 can induce DNA damage in H1650 and A549 cell lines. Moreover, combining erlotinib further augmented DNA damage by YM155, which were retarded by autophagy inhibitor 3MA, or knockdown of autophagy-related protein Beclin 1, revealing that YM155 induced DNA damage is autophagy-dependent. Similar results were also observed in vivo xenograft experiments. Therefore, combination of YM155 and erlotinib offers a promising therapeutic strategy in NSCLC with EGFR-TKI resistant phenotype.

Abstract
BACKGROUND To assess the impact of location versus number of extra-pulmonary metastatic sites (EPMS) on survival in stage IV non-small cell lung cancer (NSCLC). METHODS AND MATERIALS Retrospective analysis was conducted on patients diagnosed during 1999-2013 with stage IV, M1b (AJCC 7th edition) NSCLC using the large, institutional Glans-Look Database, which contains patient demographic, clinical, pathological, treatment, and outcome information. We assessed the impact of location and number of EPMS and identified correlates of overall survival using the Kaplan-Meier method and Cox regression. RESULTS We identified a total of 2065 NSCLC patients with EPMS. Median age was 67 (IQR 58-75) years, 52% were men, and 78% were current or former smokers. 60% had one EPMS, and 40% had two or more EPMS. Among those with only one EPMS, most frequent organ involvement included bone (40%), brain (32%), and liver (13%). Median overall survival (mOS) was worst in those with liver metastasis and best in those with adrenal metastasis (2.0 vs. 5.2 months, p = 0.015). However, outcomes based on site of organ involvement were not significantly different in multivariable analysis. Compared to patients with one EPMS, individuals with two or more EPMS experienced worse outcomes (mOS ≤ 2.9 vs. 3.9 months, p < 0.001), and were associated with worse prognosis in Cox regression analysis (HR 1.5, 95% CI 1.3-1.7, p < 0.001). CONCLUSIONS Number rather than location of EPMS is a prognostic factor in patients with stage IV M1b NSCLC. This information is relevant for accurate prognostication, stratification of participants in future clinical trials, and timely and appropriate advanced care planning.

Abstract
For the majority of patients with advanced non-small cell lung cancer (NSCLC), the standard of care remains platinum-based chemotherapy. However, cisplatin resistance is a big obstacle to the treatment, and elucidation of its mechanism is warranted. In this study, we showed that there was no difference in intracellular uptake of cisplatin or the removal of platinum-DNA adducts between a cisplatin-resistant NSCLC cell line (A549/DR) and a cisplatin-sensitive NSCLC cell line (A549). However, the capacity to repair DNA interstrand crosslinks (ICLs) and double-strand breaks (DSBs) was significantly enhanced in the A549/DR cell line compared to 3 cisplatin-sensitive cell lines. We found that the protein and mRNA expression levels of Pol η, a Y-family translesion synthesis (TLS) polymerase, were markedly increased upon cisplatin exposure in A549/DR cells compared with A549 cells. Furthermore, intracellular co-localization of Pol η and proliferation cell nuclear antigen (PCNA) induced by cisplatin or cisplatin plus gemcitabine treatment was inhibited by depleting ataxia telangiectasia mutated and Rad-3-related (ATR). Pol η depletion by siRNA sensitized A549/DR cells to cisplatin; co-depletion of Pol η and ATR further increased A549/DR cell death induced by cisplatin or cisplatin plus gemcitabine compared to depletion of Pol η or ATR alone, concomitant with inhibition of DNA ICL and DSB repair and accumulation of DNA damage. No additional sensitization effect of co-depleting Pol η and ATR was observed in A549 cells. These results demonstrate that co-inhibition of Pol η and ATR reverses the drug resistance of cisplatin-resistant NSCLC cells by blocking the repair of DNA ICLs and DSBs induced by cisplatin or cisplatin plus gemcitabine.

Factors associated with gene aberration test status and treatment decision in patients with unresectable Stage IIIB/IV nonsquamous non-small cell lung cancer: A multicenter survey in China (CTONG 1506). Lung Cancer 2018; 123:7-13. [PMID: 30089597 DOI: 10.1016/j.lungcan.2018.06.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2017] [Revised: 05/27/2018] [Accepted: 06/08/2018] [Indexed: 10/14/2022]
Abstract
OBJECTIVES This study investigated factors associated with (i) the likelihood of receiving a gene aberration test and (ii) the choice of treatment between chemotherapy and targeted therapy in patients with non-small cell lung cancer (NSCLC) in China. MATERIALS AND METHODS This cross-sectional study analyzed data previously extracted from the medical charts of patients with unresectable Stage IIIB/IV nonsquamous NSCLC discharged from one of 12 tertiary hospitals in China between August 2015 and March 2016. Logistic regressions were applied to investigate factors associated with receiving a gene aberration test and the treatment decision. RESULTS Data from 932 patients were analyzed. Patients were less likely to have a gene aberration test if they had a histologic subtype other than adenocarcinoma or a hospital waiting time for test results of >5 days. Patients were more likely to receive tyrosine kinase inhibitor (TKI) treatment than chemotherapy if they had a positive result for epidermal growth factor receptor (EGFR)/anaplastic lymphoma kinase gene aberration testing. EGFR positive patients were more likely to receive TKI treatment than chemotherapy if they did not have insurance for TKI or pemetrexed treatment, and more likely to receive chemotherapy than TKI treatment if they had a waiting time for test results of >5 days. EGFR wild-type/unknown patients receiving chemotherapy were more likely to receive pemetrexed if they attended a hospital in a developed area or had insurance for pemetrexed. CONCLUSION In this real-world setting in China, the choice of first-line treatment for advanced NSCLC was appropriately guided by gene aberration testing for most patients. However, gene aberration testing and the treatment decision were influenced by practical factors such as hospital location, the waiting time for test results, and insurance coverage, which should be addressed to ensure optimal patient care.

Abstract
BACKGROUND Necitumumab (Neci) was the first biologic approved by the FDA for use in combination with gemcitabine and cisplatin (Neci + GCis) in first-line treatment of metastatic squamous non-small cell lung cancer (msqNSCLC). The potential financial impact on a health plan of adding Neci + GCis to drug formularies may be important to value-based decision makers in the United States, given ever-tightening budget constraints. OBJECTIVE To estimate the budget impact of introducing Neci + GCis for first-line treatment of msqNSCLC from U.S. commercial and Medicare payer perspectives. METHODS The budget impact model estimates the costs of msqNSCLC before and after adoption of Neci + GCis in hypothetical U.S. commercial and Medicare health plans over a 3-year time horizon. The eligible patient population was estimated from U.S. epidemiology statistics. Clinical data were obtained from randomized clinical trials, U.S. prescribing information, and clinical guidelines. Market share projections were based on market research data. Cost data were obtained from online sources and published literature. The incremental aggregate annual health plan, per-patient-per-year (PPPY), and per-member-per-month (PMPM) costs were estimated in 2015 U.S. dollars. One-way sensitivity analyses were conducted to assess the effect of model parameters on results. RESULTS In a hypothetical 1,000,000-member commercial health plan with an estimated population of 30 msqNSCLC patients receiving first-line chemotherapy, the introduction of Neci + GCis at an initial market share of approximately 5% had an overall year 1 incremental budget impact of $88,394 ($3,177 PPPY, $0.007 PMPM), representing a 2.9% cost increase and reaching $304,079 ($10,397 PPPY, $0.025 PMPM) or a 7.4% cost increase at a market share of 14.7% in year 3. This increase in total costs was largely attributable to Neci drug costs and, in part, due to longer survival and treatment duration for patients treated with Neci+GCis. Overall, treatment costs increased by $81,812 (13.5%), and disease costs increased by $7,951 (0.4%), whereas adverse event costs decreased by $1,368 (0.5%) in year 1. From the Medicare perspective, the overall year 1 incremental budget impact was $438,056 ($0.037 PMPM, $3,112 PPPY), representing a 3.0% cost increase. The higher incremental budget in Medicare, compared with commercial plans, was due to higher msqNSCLC incidence in the older Medicare patients (154 vs. 30 patients, respectively). Results were most sensitive to Neci drug costs. CONCLUSIONS Based on projected market shares, coverage for first-line therapy with Neci + GCis appeared to modestly affect overall U.S. health care budgets for msqNSCLC-related care. Given the small eligible patient population, the PMPM budgetary impact on a commercial health plan of reimbursing Neci + GCis in the first year was less than $0.01, rising with increased use of Neci + GCis to $0.025 in the third year. The real-world effect of Neci + GCis needs to be evaluated to validate this analysis; however, these findings may help policymakers in making coverage decisions for Neci + GCis.

Validity of Targeted Next-Generation Sequencing in Routine Care for Identifying Clinically Relevant Molecular Profiles in Non-Small-Cell Lung Cancer: Results of a 2-Year Experience on 1343 Samples. J Mol Diagn 2018; 20:550-564.

Abstract
Theranostic assays are based on single-gene testing, but the ability of next-generation sequencing (NGS) to interrogate numerous genetic alterations will progressively replace single-gene assays. Although NGS was evaluated to screen for theranostic mutations, its usefulness in clinical practice on large series of samples remains to be demonstrated. NGS performance was assessed following guidelines. TaqMan probes and NGS were compared for their ability to detect EGFR and KRAS mutations, and NGS mutation profiles were analyzed on a large series of non-small-cell lung cancers (n = 1343). The R2 correlation between expected and measured allelic ratio, using commercial samples, was >0.96. Mutation detection threshold was 2% for 10 ng of DNA input. κ Scores for TaqMan versus NGS were 0.99 (95% CI, 0.97-1.00) for EGFR and 0.98 (95% CI, 0.97-1.00) for KRAS after exclusion of rare EGFR (n = 40) and KRAS (n = 60) mutations. NGS identified 693 and 292 mutations in validated and potential oncogenic drivers, respectively. Significant associations were found between EGFR and PI3KCA or CTNNB1 and between KRAS and STK11. Potential oncogenic driver mutations or gene amplifications were more frequent in validated oncogenic driver nonmutated samples. This work is a proof of concept that targeted NGS is accessible in routine screening, including large screening, at reasonable cost. Clinical data should be collected and implemented in specific databases to make molecular data meaningful for direct patients' benefit.

Abstract
Lung tumours have a high incidence and cause many deaths worldwide. Despite progresses in treatment with targeted therapies and immunotherapies, the global 5-year survival rate remains low. In this context, inhaled chemotherapy could provide a means to intensify current therapeutic modalities. This review is based on clinical studies of inhaled chemotherapy against lung tumours. The advantages of this approach in terms of pharmacokinetic ratio and therapeutic index are presented as well as the limitations including contraindications and pulmonary side effects. Moreover, the challenges linked to technical aspects around administration are identified (inhalation device and facilities to limit aerosol propagation and exposure of healthcare professionals). The current developments proposed to overcome these challenges are described briefly. Also discussed are the potential applications for the distribution of the inhaled anticancer drug into tumour-bearing respiratory tracts and finally the potential indications for current therapeutic modalities.

Abstract
Lung cancer is the leading cause of cancer deaths and its incidence continues to increase. Emerging therapies as part of a multimodal approach are making more patients eligible for surgical resection. As more surgeons are treating locally advanced non-small cell lung cancer they find themselves recommending pneumonectomy as the surgical component of the multidisciplinary plan. Performing a pneumonectomy is technically demanding and is associated with many potential perioperative comorbidities. With the proper preparation, experience, and attention to perioperative care, pneumonectomy can be carried out safely with excellent outcomes and a good quality of life.

Abstract
Background TIPE3 (TNFAIP8L3), a transfer protein for lipid second messengers, is upregulated in human lung cancer tissues. The most popular lung cancer is non-small cell lung cancer (NSCLC) with high incidences and low survival rates, while the roles of TIPE3 in NSCLC remain largely unknown. Methods TIPE3 expression was examined in tissue chips from patients with NSCLC using immunohistochemistry; the correlation of plasma membrane expression of TIPE3 with T stage of NSCLC was analyzed. After endogenous TIPE3 was silenced via siRNA, or TIPE3 with N or C-terminal flag was overexpressed via transient or stable transfection, human NSCLC cells were assayed for the proliferation and migration, respectively. NSCLC cells, in which TIPE3 with C-terminal flag was stably transfected, were inoculated into mice to establish xenograft tumors, the tumor growth and the expression of TIPE3 in tumor tissues were examined. Results TIPE3 was broadly expressed in lung tissues of patients with NSCLC. The plasma membrane expression of TIPE3 was positively correlated with the T stage of NSCLC. Knockdown of endogenous TIPE3, which was predominantly expressed in the plasma membrane, inhibited the proliferation and migration of NSCLC cells. While transient overexpression of TIPE3 with N-terminal flag, which was mostly trapped in the cytoplasm, inhibited the growth and migration of NSCLC cells accompanied by inactivation of AKT and ERK. In contrast, stable overexpression of TIPE3 with C-terminal flag, which could be localized in the plasma membrane, markedly promoted the growth and migration of NSCLC cells through activation of AKT and ERK. Notably, in xenograft tumor models established with NSCLC cells, stable overexpression of TIPE3 with C-terminal flag in NSCLC cells significantly promoted the tumor growth and enhanced the expression and plasma membrane localization of TIPE3 in tumor tissues. Conclusion This study demonstrates that human TIPE3 promotes the proliferation and migration of NSCLC cells depending on its localization on plasma membrane, whereas cytoplasmic TIPE3 may exert a negative function. Thus, manipulating the subcellular location of TIPE3 can be a promising strategy for NSCLC therapy.

Severe adverse events impact overall survival and costs in elderly patients with advanced non-small cell lung cancer on second-line therapy. Lung Cancer 2018; 119:112-119.

Abstract
OBJECTIVES Elderly patients with advanced non-small lung cancer (aNSCLC) represent a high-risk patient population due to disease burden, comorbidities, and performance status, particularly after progressing on first-line therapy. Among elderly patients who receive second-line therapy, treatment related toxicities can have substantial impact on both clinical and economic outcomes. This study assessed the impact of severe adverse events (AEs) during second-line therapy on overall survival (OS) and all-cause heathcare costs in elderly with aNSCLC. MATERIALS AND METHODS Patients with aNSCLC aged ≥65 years who initiated second-line chemotherapy/targeted therapy were identified in the SEER-Medicare database (2007-2011). Fifty-seven AEs were identified by literature review and consultation with two oncologists. Severe AEs were defined as AEs that required a hospitalization and were operationalized based on AE diagnosis(es) recorded during hospitalizations. OS post-second-line initiation and healthcare costs during second-line were compared between patients with and without severe AEs. RESULTS Among 3967 patients initiating second-line therapy, 1624 (41%) had ≥1 severe AE, where hypertension (26%), anemia (24%), and pneumonia (23%) were most commonly reported. Patients with and without severe AEs had similar demographic and cancer characteristics at diagnosis and similar second-line treatment regimens, but patients with severe AEs had more comorbidities at second-line initiation. Median OS was lower in patients with versus without severe AEs (6 vs. 11 months). After multivariate adjustment, hazard of death was more than twice higher in patients with versus without severe AEs (adjusted hazard ratio [HR] 2.31, 95% CI 2.16-2.47). Healthcare costs were more than twice higher in patients with versus without severe AEs ($16,135 vs. $7559 per-patient-per-month). CONCLUSION Severe AEs among elderly patients with aNSCLC treated with second-line chemotherapy/targeted therapy were found to be associated with decreased OS and increased healthcare costs. Results suggest a potential link between severe AEs in second-line treated aNSCLC elderly and patient survival and economic burden to the healthcare system.

The impact of EGFR mutations on the incidence and survival of stages I to III NSCLC patients with subsequent brain metastasis. PLoS One 2018; 13:e0192161.

Abstract
Previous studies have demonstrated the association between EGFR mutations and distant metastasis. However, the association for subsequent brain metastasis (BM) in stages I-III non-small cell lung cancer (NSCLC) patients remains inconclusive. We conducted a retrospective analysis to clarify the impact of EGFR mutations on the incidence of BM and associated survival in patients with stage I-III NSCLC. A total of 491 patients screened for EGFR mutations were retrospectively enrolled. Brain MRI or CT was used to detect the BM. Cumulative incidence of subsequent BM and overall survival (OS) after diagnosis of BM were estimated by the Kaplan-Meier method and compared using log-rank test. We performed Cox proportional hazard regression for predictors of subsequent BM and determinants of OS after BM. The cumulative incidence of BM seemed higher in patients harboring EGFR mutations than those without EGFR mutations although it did not reach statistical significance (hazard ratio [HR] = 1.75, 95% confidence interval [CI] = 0.73~1.81). After adjusting possible confounders, including age, smoking, stage, and tumor size, EGFR mutation became one of the predictors for subsequent BM (HR = 1.89, 95% CI = 1.12~3.17, p = 0.017). Though there was no statistical difference in survival after BM between patients with EGFR mutations and wild-type EGFR (median survival: 17.8 vs. 12.2 months, HR = 0.79, 95% CI = 0.45–1.40), patients with EGFR 19 deletion (Del) tended to have a longer survival after BM than the non-EGFR 19 Del group (median survival: 29.4 vs. 14.3 months, HR 0.58, 95% CI = 0.32–1.09, p = 0.089). In conclusion, our data suggested EGFR mutation to be one of the predictors for subsequent BM in stage I-III patients. Given the small sample size, more studies are warranted to corroborate our results.

Abstract
Importance Patterns-of-failure studies suggest that in metastatic non-small-cell lung cancer (NSCLC) sites of gross disease at presentation are the first to progress when treated with chemotherapy. This knowledge has led to increased adoption of local ablative radiation therapy in patients with stage IV NSCLC, though prospective randomized evidence is limited. Objective To determine if intervening with noninvasive stereotactic ablative radiotherapy (SAbR) prior to maintenance chemotherapy in patients with non-progressive limited metastatic NSCLC after induction therapy led to significant improvements in progression-free survival (PFS). Design, Setting, and Participants This is a single-institution randomized phase 2 study of maintenance chemotherapy alone vs SAbR followed by maintenance chemotherapy for patients with limited metastatic NSCLC (primary plus up to 5 metastatic sites) whose tumors did not possess EGFR-targetable or ALK-targetable mutations but did achieve a partial response or stable disease after induction chemotherapy. Interventions Maintenance chemotherapy or SAbR to all sites of gross disease (including SAbR or hypofractionated radiation to the primary) followed by maintenance chemotherapy. Main Outcomes and Measures The primary end point was PFS; secondary end points included toxic effects, local and distant tumor control, patterns of failure, and overall survival. Results A total of 29 patients (9 women and 20 men) were enrolled; 14 patients (median [range] age, 63.5 [51.0-78.0] years) were allocated to the SAbR-plus-maintenance chemotherapy arm, and 15 patients (median [range] age, 70.0 [51.0-79.0] years) were allocated to the maintenance chemotherapy-alone arm. The trial was stopped to accrual early after an interim analysis found a significant improvement in PFS in the SAbR-plus-maintenance chemotherapy arm of 9.7 months vs 3.5 months in the maintenance chemotherapy-alone arm (P = .01). Toxic effects were similar in both arms. There were no in-field failures with fewer overall recurrences in the SAbR arm while those patients receiving maintenance therapy alone had progression at existing sites of disease and distantly. Conclusions and Relevance Consolidative SAbR prior to maintenance chemotherapy appeared beneficial, nearly tripling PFS in patients with limited metastatic NSCLC compared with maintenance chemotherapy alone, with no difference in toxic effects. The irradiation prevented local failures in original disease, the most likely sites of first recurrence. Furthermore, PFS for patients with limited metastatic disease appeared similar to those patients with a greater metastatic burden, further arguing for the potential benefits of local therapy in limited metastatic settings.

Abstract
Lung cancer is the number one cause of cancer-related death in both men and women. However, over the last few years, we have witnessed improved outcomes that are largely attributable to early detection, increased efforts in tobacco control, improved surgical approaches, and the development of novel targeted therapies. Currently, there are several novel therapies in clinical practice, including those targeting actionable mutations and more recently immunotherapeutic agents. Immunotherapy represents the most significant step forward in eradicating this deadly disease. Given the ever-changing landscape of lung cancer management, here we present an overview of the most recent advances in the management of non-small cell lung cancer.

Abstract
It has been demonstrated that REV3, the catalytic subunit of the translesion synthesis (TLS) polymerase ζ, play an important role in DNA damage response (DDR) induced by cisplatin, and Ataxia-telangietasia mutated and Rad-3-related (ATR) knase is a central player in activating cell cycle checkpoint, stabilizing replication forks, regulating DDR, and promoting repair of DNA damage caused by cisplatin. Cancer cells deficient in either one of REV3 and ATR are more sensitive to cisplatin. However, whether co-inhibition of REV3 and ATR can further increase sensitivity of non-small cell lung cancer (NSCLC) cells to cisplatin is not clear. In this study, we show that REV3 knockdown combined with ATR inhibition further enhance cytotoxicity of cisplatin in NSCLC cells, including cisplatin-sensitive and -resistant cell lines, compared to individual knockdown of REV3 or ATR, which are accompanied by markedly caspase-dependent apoptosis response, pronounced DNA damage accumulation and severe impediment of interstrand crosslink (ICL), and double strand break (DSB) repair. Our results suggest that REV3 knockdown synergize strongly with ATR inhibition to significantly increase sensitivity of cisplatin in NSCLC cells by inhibiting ICL and DSB repair. Thus simultaneously targeting REV3 and ATR may represent one approach to overcome cisplatin resistance and improve chemotherapeutic efficacy in NSCLC treatment.

Abstract
Background The aim of this retrospective study was to review recurrence patterns of stage I non-small-cell lung cancer and identify prognostic factors for post-recurrence survival. Methods Among 940 patients with pathological stage I non-small-cell lung cancer who underwent curative resection, 261 experienced a recurrence; of these, 188 had adenocarcinoma and 62 had squamous cell carcinoma. Oligo-recurrence was defined as 1-3 recurrent lesions restricted to a single organ. Potentially curative local treatment included surgery, stereotactic radiotherapy, and photodynamic therapy. Results The median follow-up duration was 65 months (range 4-186 months). The most common site of recurrence was the lung in 145 patients, followed by mediastinal lymph nodes in 49, pleura in 30, and brain in 27. Local treatment for recurrent tumors included surgery in 59 patients, stereotactic radiotherapy in 46, photodynamic therapy in 2, and other radiotherapy in 41. Seventy-eight patients received chemotherapy only, and 35 received conservative treatment. Among 125 patients who were evaluated for an epidermal growth factor receptor gene mutation, 31 were treated with epidermal growth factor receptor-tyrosine kinase inhibitor. The 3- and 5-year post-recurrence survival rates were 49.1% and 33.8%, respectively. Age at recurrence, adenocarcinoma cell type, disease-free interval, epidermal growth factor receptor-tyrosine kinase inhibitor treatment, and potentially curative local treatment were independent prognostic factors for survival in multivariate analysis. Conclusions Local treatment for recurrence should be considered in selected candidates, and use of epidermal growth factor receptor-tyrosine kinase inhibitor I is reasonable if an epidermal growth factor receptor mutation is detected.

Abstract
PURPOSE OF REVIEW Using chemotherapy in elderly nonsmall cell lung cancer (NSCLC) patients is often challenging given concerns of treatment-related toxicity. However, data have demonstrated that chemotherapy can lead to improved survival in this age group. In this review, we summarize existing data and discuss the role of chemotherapy in elderly patients with localized, locally advanced, and metastatic NSCLC. RECENT FINDINGS Clear evidence-based guidelines for chemotherapy management in elderly patients is lacking given the limited prospective data available. However, there are more clinical trials investigating optimal chemotherapy agents and dosing schedules specific to the elderly. Comprehensive geriatric assessment-directed interventions are also being prospectively investigated to improve treatment selection for elderly patients. SUMMARY Chronological age should not be a limiting factor for chemotherapy use in elderly NSCLC patients. Several studies have demonstrated similar survival benefits than in younger patients when chemotherapy is given as adjuvant treatment for localized disease; part of definitive treatment with radiation in locally advanced disease; and palliative treatment for advanced NSCLC, however, at the cost of greater toxicity. Tolerability of chemotherapy in this heterogeneous group can be difficult to predict. Therefore, therapeutic decisions should be individualized based on performance status. Comprehensive geriatric assessment should be used to supplement performance status measures to minimize both under and overtreatment.

Abstract
Liquid biopsy is a blood test that detects evidence of cancer cells or tumor DNA in the circulation. Despite complicated collection methods and the requirement for technique-dependent platforms, it has generated substantial interest due, in part, to its potential to detect driver oncogenes such as epidermal growth factor receptor (EGFR) mutants in lung cancer. This technology is advancing rapidly and is being incorporated into numerous EGFR tyrosine kinase inhibitor (EGFR-TKI) development programs. It appears ready for integration into clinical care. Recent studies have demonstrated that biological fluids such as saliva and urine can also be used for detecting EGFR mutant DNA through application other user-friendly techniques. This review focuses on the clinical application of liquid biopsies to lung cancer genotyping, including EGFR and other targets of genotype-directed therapy and compares multiple platforms used for liquid biopsy.

Enhanced antitumor effect on intrapulmonary tumors of docetaxel lung-targeted liposomes in a rabbit model of VX2 orthotopic lung cancer. Sci Rep 2017; 7:10069.

Abstract
Allergic reactions and severe systemic toxicity are two major challenges for the clinical application of docetaxel (DTX) for treatment of non-small-cell lung cancer (NSCLC). We developed a novel lung-targeted DTX-loaded liposome (DTX-LP), an efficient drug delivery system, with a patented DBaumNC technology to overcome these deficiencies. In the present study, we describe the targeting activity, tumor inhibition rate (TIR), survival, pathology, tumor apoptosis and metabolism of DTX after intravenous injection of DTX-LP compared to the DTX injection (DTX-IN) formulation based on the VX2 orthotopic lung cancer rabbit model. Biodistribution studies revealed the highest accumulation in lung and tumor within 12 h after the injection of DTX-LP. The increased TIR indicates that the growth of tumor was slowed. Pathology tests demonstrated that DTX-LP can reduce metastasis and toxicity to non-targeted organs, leading to greatly extended survival time and improved survival of tumor-bearing rabbits. Flow cytometry and immunohistochemistry confirmed that DTX-LP is highly efficacious in tumor tissue, leading to a significant increase of tumor apoptosis and decrease of proliferation and angiogenesis. The results from this study demonstrate the increased intrapulmonary tumor targeting activity, enhanced antitumor effect and reduced toxicity of DTX-LP compared to DTX-IN and highlight its clinical prospects for NSCLC therapy.

Abstract
Background In recent years, systemic chemotherapy and molecular targeted therapy have become standard first-line treatments for locally advanced or metastatic nonsquamous non-small cell lung cancer (NSCLC). The objective of this survey was to investigate first-line anticancer treatment patterns and gene aberration test status of patients with advanced nonsquamous NSCLC in China. Methods Patients included in this study had unresectable Stage IIIB/IV nonsquamous NSCLC and were admitted during August 2015 to March 2016 into one of 12 tertiary hospitals throughout China for first-line anticancer treatment. Patient data (demographics, NSCLC histologic type, Eastern Cooperative Oncology Group [ECOG] Performance Status [PS], gene aberration test and results [if performed], and first-line anticancer treatment regimen) were extracted from medical charts and entered into Medical Record Abstraction Forms (MERAFs), which were collated for analysis. Results Overall, 1041 MERAFs were collected and data from 932 MERAFs were included for analysis. Patients with unresectable Stage IIIB/IV nonsquamous NSCLC had a median age of 59 years, 56.4% were male, 58.2% were never smokers, 95.0% had adenocarcinoma, and 92.9% had an ECOG PS ≤1. A total of 665 (71.4%) patients had gene aberration tests; 46.5% (309/665) had epidermal growth factor receptor (EGFR) gene mutations, 11.5% (48/416) had anaplastic lymphoma kinase (ALK) gene fusions, and 0.8% (1/128) had a c-ros oncogene 1 gene fusion. The most common first-line treatment regimen for unresectable Stage IIIB/IV nonsquamous NSCLC was chemotherapy (72.5%, 676/932), followed by tyrosine kinase inhibitors (TKIs; 26.1%, 243/932), and TKIs plus chemotherapy (1.4%, 13/932). Most chemotherapy regimens were platinum-doublet regimens (93.5%, 631/676) and pemetrexed was the most common nonplatinum chemotherapy-backbone agent (70.2%, 443/631) in platinum-doublet regimens. Most EGFR mutation-positive patients (66.3%, 205/309) were treated with EGFR-TKIs. Conclusions Findings from our survey of 12 tertiary hospitals throughout China showed an increased rate of gene aberration testing, compared with those rates reported in previous surveys, for patients with advanced nonsquamous NSCLC. In addition, pemetrexed/platinum-doublet chemotherapy was the predominant first-line chemotherapy regimen for this population. Most patients were treated based on their gene aberration test status and results.

Abstract
Brain metastases are usual in non-small-cell lung cancer (NSCLC) with poor prognosis and few available therapeutic options. This retrospective study aims to evaluate the efficacy of epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) against brain metastases from NSCLC harboring activating EGFR mutation. A total of 148 patients with brain metastases from EGFR mutation-positive NSCLC were analyzed retrospectively. The patients were orally given gefitinib (250 mg) or erlotinib (150 mg) once a day until intracranial disease progression, death, or intolerable side effects. A survival analysis was done using the Kaplan–Meier analysis and log-rank test. Objective response rate and disease control rate within brain lesions were 36.5% and 87.2%, respectively, with a median progression-free survival (PFS) and overall survival (OS) of 11.2 months (95% confidence interval [CI], 10.1–12.3) and 13.6 months (95% CI, 12.3–14.9), respectively. The patients’ characteristics were not statistically associated with PFS and OS. EGFR-TKIs showed promising antitumor activity against brain metastases in NSCLC patients with activating EGFR mutation and might be the treatment choice in this clinical setting.

Abstract
OBJECTIVE Predicting the survival rate for patients with cancer is currently performed using the TNM Classification of Malignant Tumors (TNM). Identifying accurate prognostic markers of survival would allow better treatment stratification between more aggressive treatment strategies or palliation. This is especially relevant for patients with spinal metastases, who all have identical TNM staging and whose surgical decision-making is potentially complex. Analytical morphometrics quantifies patient frailty by measuring lean muscle mass and can predict risk for postoperative morbidity after lumbar spine surgery. This study evaluates whether morphometrics can be predictive of survival in patients with spinal metastases. METHODS Utilizing a retrospective registry of patients with spinal metastases who had undergone stereotactic body radiation therapy, the authors identified patients with primary lung cancer. Morphometric measurements were taken of the psoas muscle using CT of the lumbar spine. Additional morphometrics were taken of the L-4 vertebral body. Patients were stratified into tertiles based on psoas muscle area. The primary outcome measure was overall survival, which was measured from the date of the patient's CT scan to date of death. RESULTS A total of 168 patients were identified, with 54% male and 54% having multiple-level metastases. The median survival for all patients was 185.5 days (95% confidence interval [CI] 146-228 days). Survival was not associated with age, sex, or the number of levels of metastasis. Patients in the smallest tertile for the left psoas area had significantly shorter survival compared with a combination of the other two tertiles: 139 days versus 222 days, respectively, hazard ratio (HR) 1.47, 95% CI 1.06-2.04, p = 0.007. Total psoas tertiles were not predictive of mortality, but patients whose total psoas size was below the median size had significantly shorter survival compared with those greater than the median size: 146 days versus 253.5 days, respectively, HR 1.43, 95% CI 1.05-1.94, p = 0.025. To try to differentiate small body habitus from frailty, the ratio of psoas muscle area to vertebral body area was calculated. Total psoas size became predictive of mortality when normalized to vertebral body ratio, with patients in the lowest tertile having significantly shorter survival (p = 0.017). Left psoas to vertebral body ratio was also predictive of mortality in patients within the lowest tertile (p = 0.021). Right psoas size was not predictive of mortality in any calculations. CONCLUSIONS In patients with lung cancer metastases to the spine, morphometric analysis of psoas muscle and vertebral body size can be used to identify patients who are at risk for shorter survival. This information should be used to select patients who are appropriate candidates for surgery and for the tailoring of oncological treatment regimens.

Abstract
While conventional treatment relies on protracted courses of therapy using relatively small dose-per-fraction sizes of 1.8-2Gy, there is substantial evidence gathered over decades that this may not be the optimal approach for all targetable disease. Stereotactic ablative body radiosurgery (SABR) or stereotactic body radiation therapy (SBRT) is a technique which uses precise targeting to deliver high doses of radiation capable of ablating tumors directly. In this review, we will discuss the justification for and techniques used to deliver ablative doses to improve treatment outcomes, interactions with biological and immunologic therapy, and special procedures to spare normal tissue, which have facilitated the expanding role for these techniques in the management of a wide range of malignant histologies and disease states.

Capilliposide from Lysimachia capillipes inhibits AKT activation and restores gefitinib sensitivity in human non-small cell lung cancer cells with acquired gefitinib resistance. Acta Pharmacol Sin 2017; 38:100-109.

Abstract
Most gefitinib-treated patients with non-small cell lung cancer (NSCLC) would eventually develop resistance. Lysimachia capillipes (LC) capilliposide extracts from LC Hemsl. show both in vitro and in vivo anti-cancer effects. In this study we investigated whether LC capilliposide in combination with gefitinib could overcome the resistance of NSCLC cells to gefitinib and identified the signaling pathways involved. Treatment with LC capilliposide alone inhibited the growth of a panel of NSCLC cell lines (PC-9, H460, H1975, H1299 and PC-9-GR) sensitive or resistant to gefitinib with IC50 values in the range of μg/mL. In the gefitinib-resistant PC-9-GR cells (which have a T790M EGFR mutation), LC capilliposide (at the IC30, i.e.1.2 μg/mL) markedly enhanced the inhibitory effects of gefitinib with its IC50 value being decreased from 6.80±1.00 to 0.77±0.12 μmol/L. By using the median effect analysis we showed that combination treatment of LC capilliposide and gefitinib could restore gefitinib sensitivity in PC-9-GR cells. Furthermore, LC capilliposide (1.2 μg/mL) significantly increased the apoptotic responses to gefitinib (0.77 μmol/L) in PC-9-GR cells, but did not affect gefitinib-induced G0/G1 arrest. Moreover, LC capilliposide (1.2 μg/mL) in combination with gefitinib (0.77, 1.0 μmol/L) markedly decreased the phosphorylation of the EGFR downstream signaling molecule AKT, which neither LC capilliposide nor gefitinib alone affected. In PC-9-GR cells with siRNA knockdown of AKT, addition of LC capilliposide was unable to increase gefitinib sensitivity. In a PC-9-GR xenograft mouse model, combination treatment with LC capilliposide (15 mg·kg-1·d-1, ip) and gefitinib (50 mg·kg-1·d-1, ip) dramatically enhanced tumor growth suppression (with a TGI of 109.3%), compared with TGIs of 22.6% and 56.6%, respectively, in mice were treated with LC capilliposide or gefitinib alone. LC capilliposide can restore the cells' sensitivity to gefitinib through modulation of pAKT levels, suggesting that a combination of LC capilliposide and gefitinib may be a promising therapeutic strategy to overcome gefitinib resistance in NSCLCs with a T790M mutation.

Current clinical diagnostic methods lack the specificity in detecting lung cancer patients. The issue is particularly critical for stage I and II patients. Considerable evidence showed microRNA plays a very important role in lung carcinogenesis. Here, we identified a panel of 41 miRNAs significantly elevated in patients with lung cancer, of which eight miRNAs were further validated in an independent sample cohort. Classification analysis using the panel of eight miRNAs generated a discriminatory power of 93.3 % sensitivity and 93.8 % specificity in separating non-small-cell lung cancer (NSCLC) patients from normal controls, indicating the miRNAs have a potential clinical utility in discriminating NSCLC. Interestingly, miR-1244 was found significantly elevated in the serum samples of lung cancer patients, and the test characteristics of the single miRNA were area under the curve (AUC) of 0.832 in NSCLC vs healthy controls, and 0.861 in NSCLC vs patients with unidentified pulmonary nodules. This is the first study showing serum miR-1244 could be a biomarker to screen lung cancer patients from the high-risk population.

Abstract
Advanced non-small cell lung cancer (NSCLC) has long been a diagnosis with few treatment options and poor outcomes. However, recent discoveries about the molecular biology of NSCLC are changing the way it is treated. Driver mutations that cause uncontrolled cancer cell proliferation have been discovered in some types of NSCLC. This has led to the discovery of therapies that can target a specific driver mutation in advanced NSCLC and halt cancer progression. This article reviews standard treatment of NSCLC and explores the targetable mutations of NSCLC, available targeted treatments, treatment obstacles, and the future of targeted therapy in NSCLC.

Abstract
BACKGROUND Platinum-based chemotherapy is the standard front-line treatment for patients with advanced non-small cell lung cancer (NSCLC). However, non-platinum combinations of third-generation chemotherapeutic agents are considered an alternative therapeutic option for patients who cannot tolerate the toxic effects of platinum compounds. In this study, the efficacy and toxicity of the combination of irinotecan plus cisplatin (IC) was compared to pemetrexed plus cisplatin (PC) regimen, in platinum-naïve patients with advanced NSCLC, who had been previously treated with the combination of a taxane plus gemcitabine. PATIENTS AND METHODS A total of 124 patients with locally advanced or metastatic NSCLC were randomly assigned to either irinotecan 110 mg/m2 on day 1 and 100 mg/m2 on day 8 plus cisplatin 80 mg/m2 on day 8 every 3 weeks (IC arm) or pemetrexed 500 mg/m2 plus cisplatin 80 mg/m2 on day 1 every 3 weeks (PC arm). The primary endpoint of the study was the overall response rate (ORR). RESULTS The ORR and median progression-free survival (PFS) in the IC arm were 18 % and 3.3 months, respectively, while in the PC arm were 19 % and 4.2 months (p = ns). Median overall survival (OS) was significantly higher in patients with PC (6.9 vs. 10.9; p = 0.013). PC regimen had a better toxicity profile compared to IC, with a statistically significant lower incidence of grade 3/4 neutropenia (3 vs. 31 %; p = 0.0001) and diarrhea (1.6 vs. 14.7 %, p = 0.018). CONCLUSIONS In patients with advanced NSCLC pretreated with docetaxel/gemcitabine, the combination of pemetrexed/cisplatin is associated with increased OS and is better tolerated than the combination of irinotecan/cisplatin and should be considered as a valid therapeutic option for platinum-naive, previously treated patients.

The functional status of DNA repair pathways determines the sensitization effect to cisplatin in non-small cell lung cancer cells. Cell Oncol (Dordr) 2016; 39:511-522.

Abstract
PURPOSE Cisplatin can cause a variety of DNA crosslink lesions including intra-strand and inter-strand crosslinks (ICLs), which are associated with the sensitivity of cancer cells to cisplatin. Here, we aimed to assess the contribution of the Fanconi anemia (FA), homologous recombination (HR) and nucleotide excision repair (NER) pathways to cisplatin resistance in non-small cell lung cancer (NSCLC)-derived cells. METHODS The expression of FA, HR and NER pathway-associated genes was assessed by RT-qPCR and Western blotting. siRNAs were used to knock down the expression of these genes. CCK-8 and flow cytometry assays were used to assess the viability and apoptotic rate of NSCLC-derived cells, respectively. Immunofluorescence and alkaline comet assays were used to assess the repair of ICLs. RESULTS We found that acquired cisplatin-resistant NSCLC-derived A549/DR cells exhibited markedly enhanced FA and HR repair pathway capacities compared to its parental A549 cells and another independent NSCLC-derived cell line, Calu-1, which possesses a moderate innate resistance to cisplatin. siRNA-mediated silencing of the FA-associated genes FANCL and RAD18 and the HR-associated genes BRCA1 and BRCA2 significantly potentiated the sensitivity of A549/DR cells to cisplatin compared to A549 and Calu-1 cells, suggesting that the acquired cisplatin resistance in A549/DR cells may be attributed to enhanced FA and HR pathway capacities responsible for ICL repair. Although we found that expression knockdown of the NER-associated genes XPA and ERCC1 sensitized the three NSCLC-derived cell lines to cisplatin, the sensitization effect was more significant in Calu-1 cells than in A549 and A549/DR cells, implying that the innate cisplatin resistance in Calu-1 cells may result from an increased NER activity. CONCLUSIONS Our results indicate that the functional status of DNA repair pathways determine the sensitivity of NSCLC cells to cisplatin. Direct targeting of the pathway that is involved in cisplatin resistance may be an effective strategy to surmount cisplatin resistance in NSCLC.

Abstract
PURPOSE The prognostic impact of baseline C-reactive protein (CRP) in non-small-cell lung cancer (NSCLC) is debated. To evaluate this issue, we performed a systematic review and meta-analysis to explore the role of CRP value in predicting early-stage NSCLC survival. METHODS Ten articles on early-stage NSCLC were eligible and included in our study. We performed a random-effects meta-analysis and assessed heterogeneity and publication bias. We pooled hazard ratio (HR) estimates and their 95% confidence intervals (CIs) on mortality for the comparison between the study-specific highest category of CRP level versus the lowest one. RESULTS In overall analysis, elevated pretreatment CRP values were significantly associated with poor overall survival (HR 1.60, 95% CI 1.30-1.97, p<0.001, I2 = 71.9%). Similar results were observed across considered strata. However, higher mortality risk was reported in studies in which CRP was combined with other factors (HR 1.96, 95% CI 1.58-2.45) and in those using a cutoff value of 3 mg/L (HR 1.89, 95% CI 1.52-2.35). CONCLUSIONS Based on our analysis, baseline high CRP level is significantly associated with poor prognosis in early-stage NSCLC. Further prospective controlled studies are needed to confirm these data.

Abstract
BACKGROUND The incidence of lung cancer is rising in developing countries like India. Due to unaffordability among the low socioeconomic status (SES) patients, there is a significant delay in seeking appropriate medical treatment due to which a high proportion of patients present in an advanced/metastatic stage and the outcomes are poor. OBJECTIVE In this study, we studied the progression-free survival (PFS) and the pharmacoeconomic benefits with the cisplatin plus etoposide (EtoP) chemo regimen and compared it with the current generation chemo regimen. MATERIALS AND METHODS We performed a retrospective analysis of metastatic nonsmall cell lung cancer patients who received one or more cycles of platinum-based chemotherapy between 2011 and 2014. RESULTS Of the 304 patients, 56.6% of the patients were of the low SES. Of the low socioeconomic group patients, 67.45% and 31.4% received etoposide and paclitaxel platinum doublet combination regimen as first line, respectively. The mean PFS with the etoposide, paclitaxel, pemetrexed, and gemcitabine platinum-based doublet regimens were 9.35, 10, 10.76, and 9.83 months, respectively. Kaplan-Meier survival curve analysis showed a statistically significant initial survival with the first line EtoP cisplatin regimen for the initial 6 months of starting chemotherapy in comparison with the other regimens. CONCLUSIONS This study showed a substantial pharmacoeconomic benefit with the cisplatin and etoposide chemo regimen in the lower socioeconomic group of patients. We believe that this is the first pharmacoeconomic study on metastatic non small cell lung treatment of great relevance to countries with limited resources.

Abstract
Nab-paclitaxel is a novel therapeutic agent, which was approved in combination with carboplatin in the first-line treatment of advanced non-small cell lung cancer (NSCLC) regardless of histologic subtype in the United States of America by the Food and Drug Administration in 2012 and by the European Commission in 2015. This approval was based on the results of a phase III clinical trial showing superior response rates compared with solvent-based paclitaxel in combination with carboplatin. This review will focus on the early development and clinical data to date supporting the use of nab-paclitaxel in advanced NSCLC. The clinical question central to this review is whether nab-paclitaxel has a place in the current therapeutic landscape of advanced NSCLC.

Abstract
PURPOSE The aim of this retrospective study was to investigate the anticancer effect and toxicity of weekly administered nab-paclitaxel as a second-line chemotherapy in elderly patients with relapsed squamous non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS We retrospectively reviewed the treatment of 42 elderly patients with relapsed squamous NSCLC, who received nab-paclitaxel monotherapy as a second-line treatment from January 2010 to March 2014. A dose of 100 mg/m(2) nab-paclitaxel was administered weekly on days 1, 8, and 15, followed by 1 week of rest. The protocol was maintained for at least two cycles. RESULTS The overall response rate (ORR) and the disease control rate (DCR) were 21.43% (9/42) and 47.62% (20/42), respectively. The median progression-free survival (PFS) and overall survival (OS) were 6.6 and 10.9 months, respectively. In the subgroup analysis, there was no significant difference in ORR, DCR, PFS, and OS, accounting for the first-line therapy factors (taxane agent, radiotherapy, or surgery). There was a statistically significant difference in DCR for stages III and IV (62.96% vs 20%, P=0.008), but there was no such difference in either PFS or OS. The ORR of 29 patients receiving more than three cycles of treatment was higher than that of those receiving less than three cycles of treatment (31.03% vs 0%, P=0.038), and there was a significant difference in PFS (7.6 vs 4.9 months, P=0.004) and OS (11.7 vs 8.9 months, P=0.002). No hypersensitivity reactions or treatment-related grade 4 adverse events were reported. CONCLUSION Nab-paclitaxel monotherapy administered weekly at a dose of 100 mg/m(2) is shown to be an effective and safe regimen for elderly patients with relapsed squamous NSCLC, especially for patients with stage III disease or good performance status.

Abstract
Lung cancer is the principal cause of cancer-related mortality in the developed world, accounting for almost one-quarter of all cancer deaths. Traditional treatment algorithms have largely relied on histologic subtype and have comprised pragmatic chemotherapy regimens with limited efficacy. However, because our understanding of the molecular basis of disease in non-small cell lung cancer (NSCLC) has improved exponentially, it has become apparent that NSCLC can be radically subdivided, or molecularly characterized, based on recurrent driver mutations occurring in specific oncogenes. We know that the presence of such mutations leads to constitutive activation of aberrant signaling proteins that initiate, progress, and sustain tumorigenesis. This persistence of the malignant phenotype is referred to as "oncogene addiction." On this basis, a paradigm shift in treatment approach has occurred. Rational, targeted therapies have been developed, the first being tyrosine kinase inhibitors (TKIs), which entered the clinical arena > 10 years ago. These were tremendously successful, significantly affecting the natural history of NSCLC and improving patient outcomes. However, the benefits of these drugs are somewhat limited by the emergence of adaptive resistance mechanisms, and efforts to tackle this phenomenon are ongoing. A better understanding of all types of oncogene-driven NSCLC and the occurrence of TKI resistance will help us to further develop second- and third-generation small molecule inhibitors and will expand our range of precision therapies for this disease.

Abstract
Non-small cell lung cancer (NSCLC) accounts for 80-90 % of cases of primary lung cancer. Although surgery is recommended as the primary treatment for early-stage NSCLC, the prognosis is unsatisfactory even when complete resection is achieved. Recent clinical trials have shown that postoperative adjuvant chemotherapy with cytotoxic agents, namely uracil-tegafur (UFT) for stage IA (>2 cm in diameter)-IB patients or cisplatin-based regimens for stage II-IIIA patients, improves the prognosis, and adjuvant chemotherapy is recommended as the "standard treatment of care." However, adjuvant chemotherapy provides only a modest 5-year survival benefit of 4 % and may sometimes be fatal. To improve the risk-benefit balance of adjuvant chemotherapy, targeting agents such as antibodies against vascular endothelial growth factor (VEGF) and tyrosine-kinase inhibitors of epidermal growth factor receptor (EGFR-TKIs) are being evaluated in ongoing adjuvant trials. Another promising approach may be the individualization of adjuvant chemotherapy based on biomarkers that may predict the prognosis or benefits associated with adjuvant chemotherapy. The current status and future perspectives of adjuvant chemotherapy for NSCLC are reviewed and discussed.

Abstract
INTRODUCTION The primary analysis of this open-label, randomized, multicenter phase 3 study revealed no significant difference in progression-free survival between pemetrexed plus cisplatin followed by maintenance gefitinib (PC/G) and gefitinib monotherapy (G) in patients with advanced nonsquamous non-small cell lung cancer (NSCLC) and unknown epidermal growth factor receptor gene (EGFR) mutation status; however, the hazard ratio favored PC/G. This report describes the final overall survival (OS) results. METHODS Chemonaive, East Asian light ex-smokers/never-smokers with advanced nonsquamous NSCLC and unknown EGFR mutation status were randomized (1:1) to PC/G (n = 118) or G (n = 118). EGFR mutation status was retrospectively determined for 76 patients, 52 (68.4%) of whom had EGFR-mutated tumors (exon 19 deletions in 26 and L858R point mutation in 24). OS was analyzed by the Kaplan-Meier method. The study was registered at ClinicalTrials.gov (NCT01017874). RESULTS Median OS was similar in the PC/G (26.9 months) and G (27.9 months) groups (hazard ratio = 0.94, 95% confidence interval: 0.68-1.31, p = 0.717). Median OS was longer with PC/G than with G in patients with EGFR wild-type tumors (28.4 versus 8.9 months) and longer with G than with PC/G in patients with EGFR-mutated tumors (45.7 versus 32.4 months), especially those with exon 19 deletions. Second-line postdiscontinuation therapy was common and included chemotherapy (PC/G, 41 of 118 [34.7%]; G, 73 of 118 [61.9%]) and rechallenge with an EGFR tyrosine kinase inhibitor (PC/G, 27 of 118 [22.9%]; G, 9 of 118 [7.6%]). CONCLUSIONS The progression-free survival and OS results from this study further demonstrate the importance of determining EGFR mutation status to select the most appropriate first-line treatment for patients with advanced NSCLC.
